[0022] Explosion-proof hand lamps are usually equipped with high-brightness LED light sources, which can provide a powerful lighting effect. This high-brightness lighting can ensure that in outdoor, nighttime, or low-light environments, workers can have sufficient visibility and brightness, thus efficiently completing work tasks. Explosion-proof hand lamps are strictly manufactured in accordance with explosion-proof standards and have excellent explosion-proof performance. In flammable and explosive environments, such as oil, chemical, and coal mines, the sparks generated by lamps may trigger explosion accidents. However, explosion-proof hand lamps can effectively prevent explosion accidents caused by the sparks or high temperatures generated by the lamps through special designs and material selections, thus ensuring the safety of workers' lives and the safe operation of equipment.

[0023] Please refer to Figure 1 , which is a schematic structural diagram of an Internet of Things-based control system in the first embodiment of this application, applied to an explosion-proof hand lamp for positioning the height of the explosion-proof hand lamp. The Internet of Things-based control system includes: a central processing module 101, a display module 102, and a pressure acquisition module 103; the output end of the pressure acquisition module 103 is connected to the input end of the central processing module 101, and the output end of the central processing module 101 is connected to the display module 102; the pressure module is used to acquire the first pressure value of the explosion-proof hand lamp at the first position and the second pressure value of the explosion-proof hand lamp at the second position, and send the first pressure value and the second pressure value to the central processing module 101; the central processing module 101 is used to calculate the height difference between the second position and the first position based on the preset pressure-height calculation rule for the first pressure value and the second pressure value, and send the height difference to the display module 102; the preset pressure-height calculation rule includes different height differences corresponding to different pressure differences; the display module 102 is used to display the height difference.

[0024] Specifically, the air pressure acquisition module 103 can be a barometer, which is used to measure the atmospheric pressure value at the location. Ensure that the barometer is in a stable state and read the accurate pressure value. Calculate according to the relationship between atmospheric pressure and altitude. Commonly used relationships are: within 3000m above sea level, for every 12 meters of elevation, the atmospheric pressure decreases by approximately 133 Pa (1 mmHg), then the height h can be expressed as: h = 12m / mmHg × (p0 - p), where p0 is the atmospheric pressure value at sea level (unit: mmHg), and p is the atmospheric pressure value at the location (unit: mmHg). If the unit is converted to Pascal, the relationship is: h = 12m × (p0 - p) / 133Pa. Another commonly used relationship is: for every 10 meters of elevation, the atmospheric pressure decreases by approximately 100 Pa, then the height h can be expressed as: h = (p0 - p) / 10, where the units of p0 and p are both Pascal. Select an appropriate relationship for calculation to obtain the height value of the location. In practical applications, since the atmospheric density decreases with increasing altitude, the coefficients in the relationship may need to be corrected. The barometer should be calibrated and maintained regularly to ensure the accuracy of the measurement results. During the measurement process, the barometer should be protected from external factors such as temperature and humidity.

[0025] The system in this embodiment obtains the first air pressure value of the explosion-proof flashlight at the first position through the air pressure module, and obtains the second air pressure value of the explosion-proof flashlight at the second position, and sends the first air pressure value and the second air pressure value to the central processing module 101; the central processing module 101 calculates the height difference between the second position and the first position based on the preset air pressure - height calculation rule for the first air pressure value and the second air pressure value, and sends the height difference to the display module 102; the display module 102 displays the height difference, thereby realizing the positioning of the height of the explosion-proof flashlight and improving the positioning accuracy.

[0026] In addition, the barometer can measure the atmospheric pressure and predict the weather conditions based on its changes. In an inflammable and explosive environment, weather changes may directly affect the safety of the workplace. For example, a decrease in air pressure may mean that the weather will turn cloudy or there will be rainfall, which may lead to an increase in humidity in the workplace, thereby increasing the risk of explosion. Through the barometer, the staff can timely understand the weather changes and take corresponding preventive measures to ensure the safety of the workplace.

[0027] In a specific embodiment, the Internet of Things-based control system further includes: an accelerometer module 104; the output end of the accelerometer module 104 is connected to the input end of the central processing module 101; the accelerometer module 104 is configured to obtain the accelerations of the explosion-proof hand lamp in different directions, and send the accelerations in different directions to the central processing module 101; the central processing module 101 is further configured to obtain the displacement of the explosion-proof hand lamp in the horizontal direction according to the accelerations in different directions, and send the displacement in the horizontal direction to the display module 102; the display module 102 is further configured to display the displacement in the horizontal direction.

[0028] Specifically, the accelerometer module 104 can be an accelerometer. Specifically, a high-precision three-axis accelerometer is used to collect acceleration data. Ensure that the accelerometer can accurately measure the acceleration in the horizontal direction. During the data collection process, keep the accelerometer fixed and stable to reduce errors. Filter the collected acceleration data to eliminate noise and interference. If necessary, calibrate the data to ensure the accuracy of the measurement. Perform the first integration on the preprocessed acceleration data to obtain velocity data. Perform the second integration on the velocity data to obtain displacement data. During the calculation process, attention needs to be paid to the starting point and ending point of the integration, as well as the integration step size. These factors will affect the accuracy of the final result. Analyze the integrated displacement data to obtain the displacement information in the horizontal direction. Among them, the higher the data sampling rate, the higher the accuracy of the integration result. Therefore, during the data collection process, it is necessary to ensure a sufficient sampling rate. Environmental factors such as temperature and humidity may affect the measurement of the accelerometer. Therefore, during the measurement process, attention needs to be paid to the changes in environmental factors and corresponding measures should be taken for compensation.

[0032] Specifically, the camera module 107 is a camera. Before video acquisition, check whether the battery power of the hand lamp is sufficient and whether the camera (if externally connected) is working properly. Ensure the stable connection between the hand lamp and the camera to avoid signal interruption or image blurring during the acquisition process. According to the instruction manual of the hand lamp, correctly turn on the hand lamp and adjust it to the appropriate video acquisition mode. Connect the camera to the hand lamp to ensure stable connection and normal signal transmission. Adjust the angle and focal length of the camera as needed to obtain the best acquisition effect. On the control interface of the hand lamp or the camera, select the option to start acquisition and start recording the video. During the acquisition process, monitor the video screen in real time to ensure that the screen is clear and stable, and make appropriate adjustments as needed. When it is necessary to end the acquisition, select the option to end the acquisition on the control interface of the hand lamp or the camera to save the recorded video file.

Specifically, by using the microphone module 109 and the speaker module 108, and realizing real-time voice calls with the preset upper computer through the 4G module.

[0035] In a specific embodiment, the Internet of Things-based control system further includes: a temperature detection module 110; the output end of the temperature detection module 110 is connected to the input end of the display module 102; the temperature detection module 110 is used to detect the temperature value of the environment where the explosion-proof hand lamp is located and send the temperature value to the display module 102; the display module 102 is further used to display the temperature value. Specifically, the working principle of the temperature detection module 110 is mainly based on the working principles of sensors such as the thermoelectric effect, thermistors, or platinum resistors. These sensors can convert temperature signals into electrical signals, and then through signal processing circuits for amplification, filtering, isolation, and linear compensation, etc., and finally output recognizable temperature values.

After the module receives the reflected signal, it determines the distance by calculating the round-trip time of the laser beam. The laser ranging module has the advantages of high accuracy and wide measurement range.

[0037] In a specific embodiment, the preset host computer can be a mobile phone terminal or a computer terminal. The mobile phone terminal can send information to the portable lamp, and can send an evacuation signal to the portable lamp. Specifically, the user can send information to a specified portable explosion-proof searchlight (such as the RJW7109 portable explosion-proof searchlight) through the mobile phone terminal APP. The information content can be text, numbers or symbols, which are used to convey instructions, reminders or notifications to the on-site personnel. In an emergency, the user can send an evacuation signal to all or specified portable lamps through the mobile phone terminal APP. After receiving the information, the portable lamp can display the received information content through its display screen or light signal (such as flashing). Specifically, after receiving the evacuation signal, the portable lamp will immediately activate a specific light mode (such as rapid flashing) to warn the on-site personnel to evacuate quickly. When receiving other information, different light modes can also be set to indicate that the information has been received. Receiving the evacuation signal is particularly important in scenarios such as emergency evacuation and accident rescue, which can significantly improve the safety and evacuation efficiency of on-site personnel.

[0038] For a portable lamp equipped with a Beidou positioning system, the user can view its movement trajectory through a Beidou-enabled computer or mobile phone APP. These trajectory data can be updated in real time and displayed on the map to help the user track the position and movement path of the portable lamp.

The mobile phone terminal APP jumps to the map interface for navigation search: When the user needs to find the specific position of a certain portable explosion-proof searchlight, they can directly jump to the map interface through the mobile phone terminal APP. On the map, the user can enter the number or name of the portable lamp, and then the mobile phone terminal APP will automatically locate the position of the portable lamp. The user can also quickly find the position where the portable lamp is located according to the navigation prompts on the map. This function is very convenient when looking for specific equipment in a complex environment, which can save a lot of time and effort.
